Earlier this week I wrote about the newly released White iPhone 4. I mentioned that with the White iPhone 5 on the way, you are best waiting until the Fall for the device on 4G than going out to buy it now. Now I have a new reason why you’d better wait: the White iPhone 4 is thicker than the black version. While it may not seem like a very big deal, the discrepancy actually creates a bit of an issue: if I buy this case, will it fit? The image above illustrates the minute difference.

Cases are normally designed using the manufacturer’s size specifications. When Apple released the iPhone 4 in White, they forgot to mention a change in thickness, adding only the following disclaimer: “Actual size and weight vary by configuration and manufacturing process.”

Apple’s SVP Phil Schiller explained that the new iPhone 4 needed extra UV protection because of its white color, which led to a slight increase in thickness. So now we have the iPhone 4 in four different sizes, with slight differences in button placement:

1. iPhone 4 – Black – AT&T | 2. iPhone 4 – Black – Verizon

3. iPhone 4 – White – AT&T | 4. iPhone 4 – White – Verizon

A bit of food for thought when buying a case (but in my opinion, yet another reason to wait until the iPhone 5 arrives this Fall).

After an incredible wait, Apple has finally released the White iPhone 4! The device, which ran into unexpected production issues last June, is available starting today in stores and online. Just like its black counterpart, it’s available in 16GB and 32GB capacities in a GSM version for AT&T’s network and a CDMA version for Verizon’s network.

In my opinion, this smartphone looks beautiful, but with the iPhone 5 on its way (slated arrival of Fall 2011), I wouldn’t recommend anyone run out and buy it. That being said, early reports suggest everyone is doing the exact opposite: whitey is already backordered online.

Photos of a White iPhone 4 surfaced yesterday via Boy Genius. The device is on T-Mobile!

In the US, iPhone’s are only available on Verizon and AT&T, so it’s unclear why the device is being tested on the T-Mobile network. Does T-Mobile have plans to offer the iPhone? Maybe, but why? T-Mobile is in negotiations for a merger into AT&T over the coming months, and if acquisition moves through, the iPhone would be made available to T-Mobile customers regardless.
